What is the difference between strategies and actions?

Question

I found in game theory these two concepts: strategies and actions. Both concepts are related to what the player will do but I can not make a distinction between the two concepts.

Answer 1

A strategy is a complete plan of action, specifying which action you would take in any possible contingency that might occur.

Intuitively, you choose actions "as you go", each time you need to make a decision, whereas a strategy got everything figured out before you start playing.
